Your Host ID

Professor Bill's LadderLab licenses are tied to a specific Windows PC. Your key will only work on that machine — it cannot be shared or used elsewhere. Download and run the utility below on the Windows computer where you plan to use LadderLab (not on Mac or Chromebook). It reads a hardware fingerprint from your machine (no installation required, nothing is transmitted) and displays a short code for you to copy and paste here.
